Why Choose This Product?

This thermal level switch NKC-H1304 is suitable for applications requiring reliable level detection under varying media conditions. The heat dissipation fin improves performance in elevated-temperature environments, while the cone-shaped probe design helps minimize material buildup. It supports multiple media types and provides flexible PNP/NPN output options for industrial automation systems.

Output Status

For level switches with PNP or NPN output configured as Normally Closed (NC):

• Green LED ON: No liquid is detected.
• Red LED ON: The probe is in contact with the liquid.

The LED indication provides a simple visual reference for monitoring the current switching status during operation.

Adjustment Method

Level Switch Calibration Procedure

1. Suspend the level switch so that the probe is not in contact with the medium.
2. Rotate the potentiometer clockwise until the red LED turns on.
3. Keep the probe suspended in air (without liquid contact).
4. Rotate the potentiometer counterclockwise until the green LED turns on.
5. Continue rotating one additional full turn counterclockwise to complete the adjustment.

Applications

Suitable for point level detection in industrial systems handling:

• Conventional liquid media
• High-viscosity liquids
• Low-static media
• Powder materials
• Medium temperatures up to 120°C
